is a set containing the members that are in all of the sets. This is spoken, "Set

A and B."
This is written, C = A ∩ B.
Properties of Intersection of Sets
||A ∩ B = B ∩ A
||The intersection of sets is commutative|
||(D ∩ E) ∩ F = D
∩ (E ∩ F)
||The intersection of sets is associative|
||(D ∩ E) ∪ F = (D
∪ F) ∩ (E ∪ F)
E) ∩ F = (D ∩ F) ∪
(E ∩ F)
|The intersection and union of sets are distributive|
